Description
Technical field
This utility model relates to nut technical field, is specially a kind of nut.
Background technology
Traditional fluted nut annular in nut body is evenly equipped with that several are protruding, forms a groove between two projections of arbitrary neighborhood, groove and pin with the use of, in order to prevent nut from loosening, but, protruding with groove fit during, it is easily deformed, causes fluted nut to damage；Meanwhile, the groove in existing fluted nut often makes plane, causes it with pin engagement process, and pin easily loosens, and then reduces stability when nut fastens.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is the nut providing a kind of structural strength big.
For achieving the above object, this utility model provides following technical scheme: a kind of nut, including nut body, nut body includes positive six prisms and the cylinder being connected, described positive six prisms and cylindrical junction are provided with arc-shaped transition joint face, positive six prisms are provided with screwed hole, described cylinder is provided with installing hole, screwed hole connects with installing hole, the centrage of screwed hole is located along the same line with the centrage of installing hole, described cylinder is provided with some bar-shaped troughs of through cylindrical body outer wall and installing hole hole wall, it is 60 degree that two bar-shaped troughs of arbitrary neighborhood intersect formed sharp angle.
Further, described bar-shaped trough includes the first side, the second side and bottom surface, and the first side is connected with bottom surface respectively with the second side, and described bottom surface includes first and second, and first intersects with second, and angulation is 90 degree.
Further, the centrage of each bar-shaped trough intersects at a point.
Further, the aperture of described installing hole is more than the aperture of screwed hole.
Further, the depth capacity of described bar-shaped trough is less than cylindrical height.
Further, the curved shape in described bottom surface.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that this utility model provides is brought: 1. by offering some bar-shaped troughs on the cylinder, and each through cylindrical body outer wall of bar-shaped trough and installing hole hole wall, and the depth capacity of bar-shaped trough is less than cylindrical height, such design, make to convex to form an entirety between adjacent two bar-shaped troughs, the phenomenon preventing the projection between adjacent two bar-shaped troughs from deforming, add structural strength.2. for the phenomenon preventing pin from loosening during coordinating with bar-shaped trough, occur also for the phenomenon preventing the solid timing stability of nut from reducing, pin and bar-shaped trough adaptation, therefore, pin is all laminating during installing with each face (the first side, the second side, first and the second face) of bar-shaped trough, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when nut is fixed reduces.3. in order to prevent the phenomenon got rusty between nut and bolt, the aperture of the ratio screwed hole set in the aperture of described installing hole is big, therefore, produces oil storage gap between installing hole and bolt, and by bar-shaped trough oil addition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional schematic of Fig. 1.
Fig. 3 is bar-shaped trough cross-sectional schematic on the A-A1 direction of Fig. 1 in embodiment 1.

Detailed description of the invention
With reference to Fig. 1-Fig. 4, this utility model is described further.
Embodiment
1
A kind of nut, including nut body 1, nut body 1 includes positive six prisms 11 and the cylinder 12 being connected, described positive six prisms 11 are provided with arc-shaped transition joint face 13 with the junction of cylinder 12, positive six prisms 11 are provided with screwed hole 111, described cylinder 12 is provided with installing hole 121, screwed hole 111 connects with installing hole 121, the centrage of screwed hole 111 is located along the same line with the centrage of installing hole 121, described cylinder 12 is provided with some bar-shaped troughs 14 of through cylinder 12 outer wall and installing hole 121 hole wall, it is 60 degree that two bar-shaped troughs 14 of arbitrary neighborhood intersect formed sharp angle.
By offering some bar-shaped troughs 14 on the cylindrical body 12, and each bar-shaped trough 14 through cylinder 12 outer wall and installing hole 121 hole wall, and the depth capacity of bar-shaped trough 14 is less than the height of cylinder 12, such design, make to convex to form an entirety between adjacent two bar-shaped troughs 14, the phenomenon preventing the projection between adjacent two bar-shaped troughs 14 from deforming, adds structural strength.
Described bar-shaped trough 14 includes the 141, second side 142 and bottom surface, the first side, first side 141 is connected with bottom surface respectively with the second side 142, described bottom surface includes the first face 143 and the second face 144, and the first face 143 is intersected with the second face 144, and angulation is 90 degree.
For the phenomenon preventing pin from loosening during coordinating with bar-shaped trough 14, occur also for the phenomenon preventing the solid timing stability of nut from reducing, pin and bar-shaped trough 14 adaptation, therefore, pin is all laminating during installing with each face (the 142, first face, the 141, second side, the first side 143 and the second face 144) of bar-shaped trough 14, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when nut is fixed reduces.
First side 141 is parallel with the second side 142, describe for convenience, the line marking C in Fig. 1 is orientated as the centrage of bar-shaped trough 14, it is 60 degree that the centrage of the two of arbitrary neighborhood bar-shaped troughs 14 intersects formed sharp angle, the number of bar-shaped trough 14 is 6, and the centrage of the most each bar-shaped trough 14 intersects at a point, therefore, pin can turn on two relative bar-shaped troughs 14, and stability is more increased.
In order to prevent the phenomenon got rusty between nut and bolt, the aperture of the ratio screwed hole 111 set in the aperture of described installing hole 121 is big, therefore, produces oil storage gap between installing hole 121 and bolt, and by bar-shaped trough 14 oil addition.
Embodiment
2
The present embodiment is substantially the same manner as Example 1, unique unlike: the curved shape in described bottom surface.
For the phenomenon preventing pin from loosening during coordinating with bar-shaped trough 14, occur also for the phenomenon preventing the solid timing stability of nut from reducing, pin and bar-shaped trough 14 adaptation, therefore, pin is all laminating during installing with each face (the 141, second side 142, the first side and the bottom surface of arc shape) of bar-shaped trough 14, position from all directions, prevent pin from loosening, be also prevented from the phenomenon generation that stability when nut is fixed reduces.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, those skilled in the art carries out common variations and alternatives in the range of technical solutions of the utility model and should be included in protection domain of the present utility model.
